Connect Amazon Prime account to multiple Twitch accounts?

To become Twitch Prime you have to connect your Twitch Acc with your Amazon Prime Acc, I did that too. Now I wanted to drive whether I could also connect my brother's Twitch Acc to the same Amazon Prime Acc so that he also has Twitch Prime. Because we only have an Amazon Prime Acc who already has 2 of them costs over 60 euro a year. I look forward to your response.

Nope, you could simply award the premiums for multiple dusting.
